I am looking for recommendations for an alternative to my Sennheiser-based headphones experience, in order to broaden my listening experiences. I really like what I already have, and I'll be keeping my Senns, but I'd like to add a 3rd option. I'm mostly looking for different headphones, likely, but I'm also likely looking for an amp that pairs well with the new cans. Here's what I have now, and how they are aligned with amp and audio source: Sennheiser HD800S/Schiit Mjolnir 2, stock tubes/Oppo 105D Sennheiser HD600/Sennheiser HDVA600/Marantz SA8004 My guess is that I'd like something that has a warmer sound than the Senns, but perhaps someone here more learned than me can offer some suggestions. I don't see my needs including an amp/DAC combo, as I am firmly tied to physical media, though perhaps someone will tell me otherwise. I don't have the budget to spend crazy money (above $5K), and would be thrilled if I could get something really nice around $2K in a headphones/amp combo buy. And again, I'm not looking to ditch what I already have, I like them a lot...just looking for a different sound, sonic variety is the spice of life. Thank you in advance.
